Signature Creation for GSS_WrapEx()

Section 3.4.2 describes the algorithm used by GSS_WrapEx() to create the signature. The signature contains the NTLMSSP_MESSAGE_SIGNATURE structure (section

The checksum is computed over the concatenated input buffers using only the input data buffers where sign==TRUE for NTLMv1 and all of the input data buffers for NTLMv2, including the cleartext data buffers.
